# This makefile is used to update templates for internationalization ("i18n")
# of ase-gui.

# INSTRUCTIONS
# ------------
#
# To update existing templates with strings from the latest python files,
# just run 'make'.
#
# To create a translation template for a new language (e.g. de_DE.UTF8), run:
#     LANG=de_DE.UTF8 make init
#
# After writing translations, you need to run 'make' again to generate the
# binary translation files loaded by the programme.
#
# Then you can run 'LANG=de_DE.UTF8 ase-gui' and your translations should be
# visible if you have a developer installation.
#
# During build, the po-files are globbed from setup.py so
# they are automatically included when you run install.

# List of files calling gettext.
